I just tried Photoshop in El Capitan Release Candidate version. And Photoshop is causing some major stuttering issues. Particularly obvious with the smooth zoom. When moving the mouse left right, it takes about 2-3 seconds before the canvas starts zooming. I tried reinstalling photoshop and delete all my preferences, but the problem still stays unchanged. I use an Retina iMac.

Please let Apple know about this bug in their new OS so they can fix it before release.

I will, But you are confident its Apple and nothing with Photoshop?
When clicking the image to zoom it works, but dragging the mouse left and right it gives you a big lag.

We'll take a look before then (and have been looking at their beta OS builds for quite some time), but only Apple can fix the bugs in Apple's OS. All we can do is document the bug for them and hope they fix it.

Just for information, incase it helps understanding the issue. The zoom still works , its only the animated zoom that takes a few seconds to respond, but you can still zoom by flicking the pen/mouse without seeing the animated transition. The reason why I didnt suspect it to be a GPU problem is that rotate the canvas which I would assume uses the same GPU technique to work still has an instant response.

The zoom uses slightly different GPU code, and is quite likely hitting a different code path in the driver that has a problem in it.
